Abyss

Biodata

Background / History

The Abyss's known history begins after the destruction of the Third Era. Mages who lost their homes entered it and became Evil Gods; they learned that at least two eras predated their own, though the Evil Gods from those eras had already gone mad. Consequently, reliable Abyss history extends only as far back as the Third Era. 419

According to Abyss rumors, it was built atop the shattered Netherworld, with the River Styx beneath it. The River Styx once erased souls' memories before reincarnation, making its reappearance in the Thirty-Third Era deeply alarming to the Evil Gods. 419

The Abyss contains numerous Witches from previous eras. As lifeforms nurtured by the Mother World's rules, Witches grow quickly, but those within the Abyss have been twisted by its laws. 275

Structure and Environment

Properties

Distortion and Corruption

The Abyss's laws distort beings that enter without protection. Hekate ordinarily needed either her Formless ability or an Evil God transformation to move within it; otherwise, her body would be warped into an Evil God. 469

• It contaminates intelligent lifeforms and can identify contaminated targets through specialized detection devices. 250
• Its corruption twists previous-era Witches while allowing some, such as the Twisted Witch, to retain a superficial human form. 275 278
• Exposure to Abyssal mist can transform mages into grotesque monsters and destabilize their minds. 487
• Netherworld power and Hekate's purification magic are highly effective against this contamination. 487

Abyss Monsters and Abyss Babies

The Abyss deploys monsters throughout the Outer Universe to spread contamination and pressure rival civilizations. 350 382

• Abyss Monsters can infect other universes and reproduce through contaminated hosts. 389 390
• Abyss Babies can rapidly absorb magic power and grow, forcing Hekate and the Heart Witch to intervene directly. 395 412
• When Hekate began locating the remaining monsters, the Evil Gods remotely compelled them to self-destruct, releasing corruptive mist across more than ten thousand locations. 487
• The Abyss also experimented with new lifeforms, including a lizard-like creature that absorbs magic power to become stronger. 401

Evil God Resurrection and Self-Destruction

Many Abyssal Evil Gods can revive after death or self-destruction. However, Hekate's curses could permanently seal their magic power and, in some cases, prevent revival entirely. 337 397

• Self-destruction became a standard defensive reaction among outer-Abyss Evil Gods because temporary death was preferable to being targeted by Hekate's curse. 444
• The Space-Time Evil God's repeated self-destructions resulted in 10% of its magic power being permanently sealed after ten days. 397
• Hekate's sustained attacks killed nearly one hundred Evil Gods by the Thirty-Third Era. 419

Fog Generation

The expanding fog was produced by the sealed Dread Fog Demon God, Nefiris. Other Evil Gods imprisoned Nefiris inside a machine that continuously extracted its power and converted it into mist. 468

• The fog interferes with the abilities of Abyssal Star Gods and obstructs investigation. 468
• It had expanded to roughly ten times its original size around the Breach of the Abyss, though it had not yet reached the present world at that point. 468
• Its spread beyond the Abyss indicated a potential long-term contamination threat to worlds outside it. 448

Inhabitants

• Abyssal Evil Gods — Former powerful beings, often from destroyed eras, who were transformed or twisted after entering the Abyss. 250 275
• Mythological and Primal Evil Gods — Ancient Evil Gods from the deepest layers; many are insane but possess powers far beyond later-era Evil Gods. 385 397
• Twisted Witches — Previous-era Witches distorted by Abyssal rules; some can maintain human-like appearances despite monstrous true forms. 275 278
• Galactic Evil Gods / Abyssal Star Gods — Stars that became Evil Gods and acted as Hekate's informants within the Abyss. Thirty-two eventually resonated with her. 325 495
• Dread Fog Demon God, Nefiris — A mad Demon God sealed in a machine and exploited as the source of the great fog. 468
• Manifested Demon God, Atrastea — A Mythological Era Evil God awakened to eliminate Hekate; instead, her madness caused her to repeatedly kill other active Abyssal Evil Gods. 385
• Disorderly Demon God, Anatoma — A Mythological Era Evil God capable of prohibiting rules and abilities. 401

Relationships

• Hekate — Principal enemy and eventual destroyer of the Abyss's outer and deep layers. Her curses, Death Power, Power of Terminus, and Formless ability made her a threat feared throughout the Abyss. 397 505
• Abyssal Star Gods — Secret informants who translated Evil God speech, provided intelligence, and aided Hekate's infiltration plans. 385 443 468
• Netherworld — The Abyss is rumored to have been constructed on the shattered Netherworld; its Primal layer remained linked to it. 419 505
• Black Tide Civilization — The Abyss aided it not out of loyalty, but to advance the Abyss's own goal of destroying the Mother World. 393
• Aether Civilization — An opposing civilization that developed contamination detection and repeatedly fought Abyss Monsters. 250 389
• Light Cone Federation — Targeted by Abyss Monster attacks and contamination, prompting research into countermeasures. 325 423

Story Role / Major Arcs

• Revelation of the Abyss Civilization — The Aether Civilization identifies the Abyss as a force capable of contaminating intelligent lifeforms and explains that its inhabitants are previous-era gods who escaped the End. 250
• Hekate's remote curse campaign — After learning that the Abyss is tied to Li Mengzhi's High Heaven Plane, Hekate begins burning identified Evil Gods from afar. The resulting deaths spread fear throughout the Abyss. 275 337
• Outer Universe infestation — Abyss Monsters and Babies appear across multiple civilizations, including the Aether Civilization, the Black Tide Civilization, and the Fifth Faction. 350 382 412
• Abyss exploration — Hekate uses Evil God transformations, clones, Formless, and Star God assistance to enter the Abyss and investigate its fog, layers, and inhabitants. 442 443 448
• Abyssal retaliation — Remaining monsters self-destruct across the Outer Universe, spreading corruption that Hekate and Moira purge with Netherworld and purification powers. 487 488
• Reclaiming Abyssal power — After evolving her Fate Talent into an Authority, Hekate destroys the outer and deep Abyss, annihilates their Evil Gods, and reclaims the Fire Authority from Hamonsys. 505

Trivia

• The Abyss's lack of visible stars originally made it difficult for Hekate to use Star-based movement and reconnaissance within it. 305 469
• The Outer Abyss became so fearful of Hekate's curse that Evil Gods would self-destruct before confirming whether they had actually been targeted. 444
• The Abyss's Star Gods were eventually revealed to have been sent there by Hekate herself through a completed time loop. 494 495
